OK first off I've had a few :beer: tonight so........From what I see there are a few things wrong in your log though they are all probably caused from the same issue. In the log the IAC is open way too far at idle but I don't think it's defective, I think it's doing what the ECM is telling it to do. This could be do to the actuator sol not doing it's job. The IAC being too far open is causing it to run way lean. (It's definately way lean though I'm not sure of the reason.) Your getting lots of knock counts and the retarded timing that goes with it. I think this is because it's way lean causing hot spots and probably pre ignition.Only thing that doesn't make sence is that it's lean at the top end mostly and the sol shouldn't effect anything much above idle. It's possible that it's run lean for some time and you just didn't know it. Does it tend to pop out the intake when you give it gas under heavy load? If I were you I would check thoroughly for vacuum leaks.Maybe tomorrow when I'm sober I'll look again.:haha:
